Accordingly, the appended claims as filed and as they may be amended are intended to embrace all such alternatives, modifications variations, improvements, and substantial equivalents.

Hereinafter, a composition according to an embodiment, a film, display device and article prepared therefrom, and a method for preparing the article will be described in further detail.

Composition

A composition according to an embodiment includes: a compound having a fluorine-containing (poly)ether group, wherein the compound is represented by Formula 1; and a heteroatom-containing cyclic silane compound represented by Formula 2 or Formula 3:

wherein, in the above formulas,

Rf is a fluorine-containing (poly)ether group,

L1 is a substituted or unsubstituted C1 to C20 alkylene group, a substituted or unsubstituted C1 to C20 oxyalkylene group, or a combination thereof,

Q1 is —C(═O)O—R₁, —C(═O)—O—C(═O)—R₂, —O—(C═O)—CR₃═CR₄R₅, —O—(C═O)—CR₆═CR₇—(C═O)—O—R₈, —O—C(═O)—O—R₉, an epoxy-containing group, or a cyclic carbonate-containing group,

p1 is an integer of 1 to 10, q1, q2, and q3 are each independently an integer of 1 to 10,

A1, A2, and A3 are each independently ═N—R_(u) or —S—,

R₁, R₂, R₅, R₈, and R₉ are each independently a substituted or unsubstituted C1 to C20 alkyl group, or a substituted or unsubstituted C6 to C20 aryl group,

R₃, R₄, R₆, and R₇ are each independently a hydrogen, a halogen atom, a hydroxy group, a substituted or unsubstituted C1 to C20 alkyl group, or a substituted or unsubstituted C6 to C20 aryl group,

R_(a), R_(b), R_(i), and R_(j) are each independently a substituted or unsubstituted C1 to C20 alkoxy group, a substituted or unsubstituted C1 to C20 alkyl group, a substituted or unsubstituted C6 to C20 aryl group, a halogen, or a hydroxy group, and

R_(c), R_(d), R_(e), R_(f), R_(g), R_(h), R_(k), R₁, R_(m), R_(n), R_(o), R_(p), R_(q), R_(r), R_(s), R_(t), and R_(u) are each independently a hydrogen, a substituted or unsubstituted C1 to C20 alkyl group, a substituted or unsubstituted C6 to C20 aryl group, or a substituted or unsubstituted C2 to C20 alkenyl group.

In the compound having a fluorine-containing (poly)ether group, wherein the compound is represented by Formula 1, at least one of R_(a) and R_(b) may be, for example, a substituted or unsubstituted C1 to C20 alkoxy group, a halogen, or a hydroxy group.

In the heteroatom-containing cyclic silane compound represented by Formula 2 or Formula 3, at least one of R_(i) and R_(j) may be, for example, a substituted or unsubstituted C1 to C20 alkoxy group, a halogen, or a hydroxy group.

The composition including the compound having a fluorine-containing (poly)ether group, wherein the compound is represented by Formula 1 and the heteroatom-containing cyclic silane compound represented by Formula 2 or Formula 3 may be used as a material for coating a surface of a substrate. When a coating film is formed on a surface of a display, the display surface may be abraded due to a contact of a finger, etc., with the passage of time, thereby lowering durability of the display. Since the composition includes both of the compound having a fluorine-containing (poly)ether group represented by Formula 1 and the heteroatom-containing cyclic silane compound represented by Formula 2 or Formula 3, in the course of forming a coating film, the heteroatom-containing cyclic silane compound is bonded to a polar functional group, such as a hydroxy group, of a substrate through a ring-opening reaction even without water. At the same time, the composition may form a heteroatom-containing terminal functional group, and the heteroatom-containing terminal functional group may function as a catalyst a hydrolysis and/or polycondensation reaction of the compound having a fluorine-containing (poly)ether group, or may be used as a reactant in a hydrolysis and/or polycondensation reaction of the compound having a fluorine-containing (poly)ether group. In an embodiment, a coating film which is more solid and has improved durability can be obtained.

Since the inside of a chamber is under vacuum, for example, in deposition or coating, the chamber is substantially in an anhydrous condition. It is difficult to carry out a hydrolysis and/or polycondensation reaction on the substrate surface by the compound having a fluorine-containing (poly)ether group, which has been vaporized inside the chamber, to a perform the hydrolysis and/or polycondensation reaction on the substrate surface by the compound having a fluorine-containing (poly)ether group. The efficiency of the hydrolysis reaction and/or the polycondensation reaction on the substrate surface is lowered during deposition or coating by using only the compound having a fluorine-containing (poly)ether group. Therefore, the durability of the coating film obtained through the hydrolysis reaction and/or polycondensation reaction may also be lowered. However, by using the composition including not only the compound having a fluorine-containing (poly)ether group but also the heteroatom-containing cyclic silane compound, the heteroatom-containing cyclic silane compound is bound to the surface of the substrate through a ring-opening reaction even in an anhydrous condition. The heteroatom-containing cyclic silane compound has a ring strain and is capable of easily forming a bond with a hydrophilic functional group on a substrate even without water.

In an embodiment, the compound produced through a ring-opening reaction of the heteroatom-containing cyclic silane compound includes a heteroatom-containing terminal functional group at a side opposite to the substrate. The heteroatom-containing terminal functional group, e.g., an amine group and/or thiol group, involves in the hydrolysis reaction and/or polycondensation reaction of the compound having a fluorine-containing (poly)ether group as a catalyst and/or a reactant. Therefore, the efficiency of the hydrolysis reaction and/or polycondensation reaction of the compound having a fluorine-containing (poly)ether group may be noticeably improved. Consequently, the durability of the obtained coating film is improved.

In an embodiment, the compound produced by the hydrolysis and/or polycondensation reaction of the compound produced through a ring-opening reaction of the heteroatom-containing cyclic silane compound represented by Formula 2 or Formula 3 and the compound produced by the hydrolysis and/or polycondensation reaction of the compound having a fluorine-containing (poly)ether group represented by Formula 1 includes a linking group capable of forming a non-covalent interaction with adjacent molecules between the fluorine-containing (poly)ether moiety and the silane group. The compounds prepared from the composition through the above-described reactions firmly maintain inter-chain interactions, and thus reduce or prevent damage and/or destruction of the bonding of the coating film due to frequent frictions. In an embodiment, the surface coating film may not be easily worn away due to the frequent frictions but may have reinforced durability. More specifically, since a non-covalent interaction, for example, a hydrogen bond, is maintained between a non-covalent electron pair of an amino group or an amide group included in the compound produced by the hydrolysis reaction and/or the polycondensation reaction of a ring-opening reaction product of the heteroatom-containing cyclic silane compound represented by Formula 2 or Formula 3 and the compound having a fluorine-containing (poly)ether group, wherein the compound is represented by Formula 1, and a hydrogen atom of an amide group included in an adjacent compound, a coating film prepared from the composition may have further improved durability.

By being used on a surface of a panel provided in a display device, the composition including a compound having a fluorine-containing (poly)ether group according to an embodiment and a heteroatom-containing cyclic silane compound may provide water repellency and an anti-fingerprint function and may provide improved wear resistance and durability. The panel provided in a display device may be, for example, a touch screen panel provided in a portable terminal, a panel provided in a liquid display device (LCD), or a panel provided in a plasma display panel (PDP).

Referring to FIG. 1, a film is formed on a substrate by coating the composition including a compound having a fluorine-containing (poly)ether group, wherein the compound is represented by Formula 1, and a heteroatom-containing cyclic silane compound represented by Formula 2 or Formula 3, is coated on a surface of the substrate. The heteroatom-containing cyclic silane compound represented by Formula 2 or Formula 3 is a compound containing a heteroatom and having a silane group. Since the cyclic silane compound has a ring strain, a ring-opening reaction may be carried out at room temperature even without water. The ring-opening reaction can be carried out at a temperature of about 40° C. or less, about 35° C. or less, or about 30° C. or less. The ring-opening reaction can be carried out at a temperature of about 0° C. to about 40° C., about 10° C. to about 35° C., or about 20° C. to about 30° C. Therefore, the silane group included in the cyclic silane compound is bonded to a substrate or an underlying layer having a polar functional group, such as a hydroxy group, through a ring-opening reaction without a hydrolysis reaction, thereby forming a monolayer, and there is no harmful byproduct generated due to hydrolysis. That is, the composition of the present invention is distinguished from the composition requiring a high temperature of about 50° C. to about 120° C. or water to be bonded to the substrate.

In an embodiment, the silane group included in the heteroatom-containing cyclic silane compound may not include a hydrolytic group. Even if a hydrolytic group is included in the silane group, the silane group included in the heteroatom-containing cyclic silane compound may easily form a bond on the substrate or the underlying layer by the ring strain, as described herein, The silane not including a hydrolytic group may be, for example, a silane substituted by a substituted or unsubstituted C1 to C20 alkyl group, or a substituted or unsubstituted C6 to C20 aryl group. In another example, the silane group may be a silane substituted by at least one hydrolytic group. By being substituted by a hydrolytic group, the silane group may be more easily bonded to the substrate or the underlying layer. The silane substituted by at least one hydrolytic group may be, for example, a silane substituted by at least one substituted or unsubstituted C1 to C20 alkoxy group, a halogen atom or a hydroxy group. During coating or deposition, the hydrolytic silane group may be bonded to a substrate or an underlying layer through a hydrolysis and/or polycondensation reaction. The bonding may be, for example, a covalent bond. By including a hydrolysable group, a hydrolytic silane group may be subjected to a hydrolysis and/or polycondensation reaction during coating of a composition, thereby forming a network including a hydrolysis product and/or a polycondensation product of silane. The hydrolysable group may include, for example, a C1-C10 alkoxy group, a halogen atom, or a hydroxy group, and examples thereof may include a C1-C8 alkoxy group, such as a methoxy group or an ethoxy group. Specifically, the methoxy group has excellent hydrolytic reactivity.

The silane group is bonded to a substrate or an underlying layer by a ring-opening reaction of the heteroatom-containing cyclic silane compound, and a heteroatom-containing functional group is disposed at an opposite side (i.e., an atmosphere side) to the substrate or the underlying layer. The heteroatom-containing functional group may be, for example, an amine group or a thiol group. The compound represented by Formula 1 is linked to the heteroatom-containing functional group through a hydrolysis and/or polycondensation reaction. The compound represented by Formula 1, for example, has a perfluoroether(poly)ether (PFPE) group as the fluorine-containing (poly)ether group, and a functional group having reactivity with respect to the heteroatom-containing functional group is linked to the PFPE group. Examples of the functional group having reactivity with respect to the heteroatom-containing functional group may include, but not limited to, an ester group, an acrylate group, an epoxy group, a malate group, an anhydride group, a cyclic carbonate group, or any suitable functional group capable of reacting with the heteroatom-containing functional group may be suitably used.

The compound produced by linking the compound represented by Formula 1 to the heteroatom-containing functional group derived from a heteroatom-containing cyclic silane compound through the hydrolysis and/or polycondensation reaction includes, for example, an amide bond. In an embodiment, a hydrogen bond is formed between amide bonds included in the produced compounds, and thus the compounds each including an amide bond may be more firmly bonded to each other. Therefore, a film formed from such a composition may have further improved abrasion resistance.

The compound represented by Formula 1 may be, for example, a compound represented by Formula 4:

Rf_(a)—O-Lf_(b)-(L1)_(p2)-Q1  Formula 4

wherein, in Formula 4,

Rf_(a) is a C1 to C20 perfluoroalkyl group,

Lf_(b) is a (poly)oxyalkylene group including a fluorine-containing C1 to C5 alkylene group,

L1 is a substituted or unsubstituted C1 to C20 alkylene group, a substituted or unsubstituted C1 to C20 oxyalkylene group, or a combination thereof,

Q1 is —C(═O)O—R₁, —C(═O)—O—C(═O)—R₂, —O—(C═O)—CR₃═CR₄R₅, —O—(C═O)—CR₆═CR₇—(C═O)—O—R₈, —O—C(═O)—O—R₉, an epoxy-containing group, or a cyclic carbonate-containing group,

p2 is an integer of 1 to 10,

A film according to an embodiment may include a ring-opening reaction product of a compound represented by Formula 2 or Formula 3, a compound including a ring-opening reaction product of the compound represented by Formula 2 or Formula 3 and the fluorine-containing (poly)ether group represented by Formula 1, or a polycondensation product of a ring-opening reaction product of the compound represented by Formula 2 or Formula 3 and a compound represented by Formula 1, or a combination thereof. By including the ring-opening reaction product, and the polycondensation product of the compound, the film may have improved durability.

In the present specification, “a ring-opening reaction product” of a compound means a resultant product obtained by a ring-opening reaction, and optionally subsequent hydrolysis and/or polycondensation, of the heteroatom-containing cyclic silane compound. The resultant product of the ring-opening reaction may be, for example, a compound bonded to a substrate. In the present specification, “a polycondensation product” of a compound means a resultant product obtained by a polycondensation reaction of a compound having a fluorine-containing (poly)ether group and a ring-opening reaction product of a cyclic silane compound.

The film may include, for example, a ring-opening reaction product of the compound represented by Formula 2 or Formula 3. The film may further include a compound represented by Formula 1.

A mixing molar ratio of the ring-opening reaction product of the compound represented by Formula 2 or Formula 3 and the compound represented by Formula 1, included in the film, may be, for example, about 1:0.1 to about 1:10, about 1:0.2 to about 1:10, about 1:0.5 to about 1:10, about 1:0.8 to about 1:10, about 1:1 to about 1:10, or about 1:1 to about 1:5.

The film may include, for example, a polycondensation product of the ring-opening reaction product of the compound represented by Formula 2 or Formula 3 and the compound represented by Formula 1. The film may be formed by forming a polycondensation product through a polycondensation reaction after the ring-opening reaction product of the heteroatom-containing cyclic silane compound is bonded to a substrate surface, an end of the ring-opening reaction product and the compound represented by Formula 1.

The film may include, for example, a polycondensation product of the compound represented by Formula 2 or Formula 3 and the compound represented by Formula 1. The film may be formed by binding a forming a polycondensation product through a cyclic silane compound with a substrate surface through a ring-opening reaction after forming a polycondensation product of the compound represented by Formula 2 or Formula 3 and the compound represented by Formula 1 through a polycondensation reaction.

The film may have a thickness of, for example, about 1 micrometer (μm) or less, about 500 nanometer (nm) or less, about 100 nm or less, about 50 nm or less, about 40 nm or less, about 30 nm or less, about 20 nm or less, or about 15 nm or less.

The film may be a non-self-supporting film that is disposed on a substrate and requires a substrate.

Anti-fingerprint coating performance of a film may be quantified by analyzing a water contact angle and/or a diiodomethane contact angle at room temperature, for example, 25° C.

A contact angle of a film may be measured using water. The film may have an improved contact angle by including a fluorine-containing (poly)ether group on a surface thereof. In an embodiment, the film may have good slipperiness and water repellency. The film may have a contact angle of, for example, about 100° or greater, about 105° or greater, about 110° or greater, or about 115° or greater, for example, about 100° to about 180°, about 105° to about 180°, about 110° to about 180°, about 115° to about 180°, or about 120° to about 180°. The contact angle may be measured by using a Sessile drop technique. A liquid used in measuring the contact angle may be water, and the contact angle may be measured by dropping a predetermined amount (about 3 microliter (μl)) of water on a film surface using a Drop Shape Analyzer (DSA100, KRUSS, Germany).

The film may maintain a high contact angle even after frequent frictions. Durability of a film may be evaluated by measuring a contact angle change after multiple times of friction. For example, after an abrasion test (5,000 times of rubbing) with a rubber eraser having a load of 1 kilogram (kg), the film may have a contact angle change of about 20° or less, about 18° or less, about 15° or less, about 12° or less, or about 10° or less, for example, about 0.5° to about 20°, about 1° to about 20°, about 1° to about 15°, about 1° to about 12°, about 1° to about 10°, or about 1° to about 5°. For example, the film may have a contact angle of about 95° or greater even after an abrasion test (1,000 times of rubbing) with a rubber eraser having a load of 1 kg. For example, the film may have a contact angle of about 50° or greater even after an abrasion test (10,000 times of rubbing) with a rubber eraser having a load of 1 kg. For example, the film may have a contact angle of about 95° to about 175°, about 75° to about 175°, about 60° to about 175°, or about 50° to about 175° even after an abrasion test (1,000 times of rubbing) with a rubber eraser having a load of 1 kg.

In an embodiment, a contact angle of a film may be measured using diiodomethane. In this case, the film may have a contact angle of, for example, about 90° or greater, about 95° or greater or about 97° or greater, for example, about 90° to about 180°, about 95° to about 180°, about 97° to about 180°, about 100° to about 170°, or about 110° to about 180°. The contact angle may be measured by using a Sessile drop technique. A liquid used in measuring the contact angle may be diiodomethane, and the contact angle may be measured by dropping a predetermined amount (about 2.7 μl) of diiodomethane on a film surface using a Drop Shape Analyzer (DSA100, KRUSS, Germany).

The obtained product was dissolved in a Novec 7200 solvent and then purified by allowing the solution to pass through silica gel, thereby obtaining CF₃O(CF₂CF₂O)_(p)(CF₂O)_(q)CF₂C(═O)NHCH₂CH═CH₂.

To a 100 ml reactor with a stirrer and a heater was injected 15 g of CF₃O(CF₂CF₂O)_(p)(CF₂O)_(q)CF₂C(═O)NHCH₂CH═CH₂, 0.73 g of trimethoxy silane and 80 microliter (μl) of a xylene solution of platinum(0)-1,3-divinyl-1,1,3,3-tetramethylsiloxane complex were added thereto, followed by stirring at 60° C. for 12 hours. Next, unreacted trimethoxy silane was removed under high-temperature vacuum conditions of 80° C. and 1 Torr using a rotary pump, and then filtered using a celite filter, thereby obtaining CF₃O(CF₂CF₂O)_(p)(CF₂O)_(q)CF₂C(═O)NHCH₂CH₂CH₂Si(OCH₃)₃ as a silane compound (C) having a fluorine-containing (poly)ether group.

Comparative Example 2: Silane Compound (D) Having Fluorine-Containing (Poly)Ether Group

A film was prepared in the same manner as in Example 1, except that a commercially available perfluoro (poly)ether silane compound (OPTOOL US509, Daikin) was used.

Evaluation Example 1: Evaluation of Durability and Slipperiness

The durability and slipperiness of each of the films prepared in Examples 1 to 7 and Comparative Examples 1 and 2 were evaluated.

Durability of a film may be evaluated by measuring a contact angle change due to friction.

An initial contact angle was evaluated by using a Sessile drop technique and measured by dropping water dropwise on each film at 25° C. with a Drop shape analyzer (DSA100, KRUSS, Germany).

Subsequently, the respective films were rubbed multiple times (5000 times (5K), 10000 times (10K), 12000 times (12K), 15000 times (15K), and 20000 times (20K)) using a polyurethane rubber eraser having a load of 1 kg and a width of 6 mm. After rubbing at 25° C., a water contact angle was measured in the same manner as the initial contact angle, and Table 1 summarizes numbers of times of rubbing, in which the water contact angle was maintained at about 100° or greater. As the number of times of rubbing increases, the film has improved durability.

The slipperiness was evaluated by measuring a coefficient of friction (COF) at 25° C. using a standard measuring method provided in the manual of a friction tester (model FPT-F1, Labthink). Some of COF measurement results are shown in Table 1.

TABLE 1 Number of Coefficient Initial times of of contact rubbing friction angle [Number (COF) [degree] of times] Example 1 0.07 117 20K Example 2 0.06 117 20K Example 3 0.06 117 10K Example 4 0.07 117 15K Example 5 0.06 117 12K Example 6 0.06 117 15K Example 7 0.07 116 10K Comparative Example 1 0.07 118 10K Comparative Example 2 0.07 118  5K

As indicated in Table 1, the numbers of times of rubbing of the films prepared in Examples 1 to 7 were all 10K or greater, in which contact angles of 100° or greater were maintained.

Specifically, the numbers of times of rubbing of the films prepared in Examples 1, 2 and 4 to 6 were all 12K or greater, and the contact angles of the films were maintained at 100° or greater.

Therefore, it was confirmed that the films prepared in Examples 1 to 7 showed improved durability against a friction, as compared with the film prepared Comparative Example 1.

The films prepared in Examples 1 to 7 showed a coefficient of friction of 0.1 or less, suggesting that good slipperiness was attained, like the films prepared in Comparative Examples 1 and 2.
